Abstract: A24.00001 : Mapping the Phase Diagram of Frustrated Quantum Magnets Using Magnetic Field, Pressure and Chemical Doping
8:00 AM–8:36 AM
The interactions that define how spins arrange themselves in a material play a fundamental role in a wide variety of physical phenomena. Frustrated quantum magnets are systems in which the exchange interactions governing the interacting spins cannot be simultaneously satisfied, leading to a highly degenerate ground state and exotic states of matter. In this talk I will discuss how chemical doping, hydrostatic pressure and application of magnetic field regulates the underlying electronic and magnetic interactions in two-dimensional geometrically frustrated systems, ultimately driving the ground state across the phase diagram and leading to emergent quantum critical phenomena. I will present our results for magnetometry, x-ray and neutron scattering experiments performed under extreme sample environments on Shastry-Sutherland model systems and rare-earth triangular antiferromagnets.
